Abstract

L'invention concerne un appareil d'imagerie capturant les images de tomographie à cohérence optique d'un objet d'essai en fonction d'une pluralité de faisceaux lumineux combinés obtenus par la combinaison d'une pluralité de faisceaux lumineux de retour provenant de l'objet d'essai irradié par une pluralité de faisceaux lumineux de mesure et une pluralité de faisceaux lumineux de référence correspondant respectivement à la pluralité de faisceaux lumineux de mesure. Ledit appareil comprend : une unité d'instruction configurée pour donner des instructions sur l'ampleur des changements de différences de longueur de trajet optique entre la pluralité de faisceaux de référence et la pluralité de faisceaux lumineux de retour; et une unité de changement configurée pour changer les différences de longueur de trajet optique en fonction de l'ampleur des changements demandés par l'unité d'instruction.
